Lays out some basics for chord diagram, starting animation stuff

- Commented out the old stuff for now
- Planning to use scale to change size
Works for creation, though they do start out black
Fixes diagram restarting each time instead of animating
Hiding only called once
Scale and center pos change works

- The thickness of the circle sections gets pretty thick at
10 qubits, but I'm not sure how to change that - I haven't
yet found a way to actually change the radii of the circles
defining the size (after many hours of searching), I've had
to use scale instead.
Fixes appearance and disappearance of chord diagram

- Fixes diagram appearing on top of first qubit
- Fixes diagram not disappearing when qubits reduced to 1 or less
- Also some comment changes
Instructions for current testing and place for new phase

- New phase is trying to show potential for partial vs. full
entanglement
Forming new matrix correctly and other things don't seem broken
Tried to make a function for exiting, didn't work, commented out

- The exiting functions were exactly the same, so I wanted to
get rid of repetition, but got an error as described.
Starting again with the partial, putting fullEntang in front
Does some setup stuff before changes
Broken, entang.entangSVG.selectAll(".part-entang .group") empty
Fixed, entang.entangSVG, I believe was being overriden, but

...I fixed that last time, or so I thought
Changed names, as before, still fixed
Implements entang.attachChord(), still working
Adds/changes some var names, takes establishing scale out for now
Enclosed some stuff in functions, still working
Adds implementation of createArcs() for updating partial entang

- Still seems to be working
Implements removeArcs(groupG) for partial entangs, still works
Implements addArcs() for partial entang, still seems to be working

- The way it goes about doing colors won't indicate which is first
anymore, but for the final thing it will probably be good. Later
might need to figure out how to get those colors back for testing
